During the year, recent flood waves of Bihar and Assam were monitored and inundation maps prepared. These maps were disseminated in near real-time (by e-mail) to the Control Room on Disaster Management, Ministry of Home Affairs, Central Water Commission and Relief Commissioners of Bihar and Assam States. 14 States in the country (AP, Bihar, Chhattisgarh, Gujarat, Haryana, Jharkhand, Karnataka, Maharashtra, Madhya Pradesh, Orissa, Rajasthan, Tamil Nadu, Uttaranchal, and UP) are covered under the project. In addition to state-wise reports, monthly summary report for the whole country and information at sub-district level for Karnataka and AP are also issued. National Agricultural Drought Assessment and Monitoring (NADAMS): Under the National Agricultural Drought Assessment & Monitoring System, ISRO is using the space data to derive normalised vegetation index, which is a measure of the vegetation vigour and water stress. Regular drought assessment reports are being generated and provided to State governments. NADAMS has been providing near real time information on agricultural conditions at district/sub-district level on a biweekly/monthly basis through regular issue of bulletins during the kharif season (June to October) and detailed reports. Landslide Hazard Zonation Mapping: An atlas containing landslide hazard and management maps was brought out for the pilgrim routes of Himachal Pradesh and Himalayas at 1:25,000 scale. The various implementing agencies have been supplied with these atlases and user workshops were conducted at Dehra Dun and Shimla towards familiarising them. Also, during the year some validation exercises were conducted using major, actual landslide data and it was found that most of these landslides occurred in the high and very-high risk zones identified in the atlas. Communication Support to Disaster Management: Towards formalising the ISRO's support to major disasters in terms of emergency communication, a Task Team of experts has studied the various equipment, coverage required, mode of operation, etc, and an action plan has been worked out, identifying the primary nodes, trigger mechanism, requirement of equipment, mode of interaction with state Governments, role of NGOs/HAMs, maintenance schedule, etc. The various follow up actions have been identified for implementing the system. Airborne Survey Facility: To meet the information needs of disaster mitigation in terms of flood-plain zoning and damage assessment, an airborne survey facility is planned to be set up in NRSA, consisting of Airborne Laser Terrain Mapping system (ALTM) and Digital Camera. Actions have been initiated to procure suitable systems. Digital Database Creation : One of the critical requirements to provide spatial information on floods and other disasters is the availability of digital database. A Technical Committee has worked out the database requirements in terms of themes, spatial scale, updating cycle, methodology and priority districts. Based on these inputs, a major project has been formulated to create digital database for selected districts in five states on a priority basis. The project is being carried out with support from RRSSCs, State Centres and NRSA. Presently, work for nine districts in Assam has been completed. International Charter on Space & Major Disasters: As a follow-up
to signing the International Charter on Space & Major Disasters,
which was initiated by major space agencies in August 2001, ISRO is
taking several steps to participate in the Charter effectively. Personnel
were identified from various ISRO Centres to support the Charter. After
successful completion of the Qualification Exercise in August 2002,
ISRO has been operationally integrated to the Charter. For realising
this goal, necessary capacity building measures such as digital database
creation, close contour data using airborne laser terrain mapper, airborne
Synthetic Aperture Radar development, querry shell development, etc,
have been initiated besides further strengthening effective coordination
with the user departments.
